SELF-FILLING- FOUNTAIN-PEN.

To all whom it may concern:

Be it known that I, JACOB ULLRIOH, a citizen of the United States,residing at Hoboken, county of Hudson, and State of New Jersey, haveinvented a new and Improved Self-Filling F ountain-Pen, of which thefollowing is a specification.

This invention relates to a self filling fountain pen of novelconstruction and more particularly to new and efficient means formanipulating and locking the presser bar which serves to compress theink bag.

In the accompanying drawing: Figure l is a longitudinal section partlyin view of a fountain pen embodying'my invention; Fig. 2 a face view ofpart of the same; Fig. 3 a cross section on line 33, Fig. 1, showing thebutton raised Fig. i a top view of the button, and Fig. 5 a side viewpartly in section of a pen showing a modification.

lVit-hin the barrel 10 of a fountain pen is inclosed an ink bag 11,along which extends the presser bar 12, as usual. From bar 12 projectsoutwardly through a corresponding aperture of barrel 10, a threaded pinorstud 13. This stud is headed as at 15, and encompassed by a hollowednut or button lat, having an inner tapped section that engages the studand an outer chamber that encompasses the upper headed end of said stud.Head 15 prevents the button from becoming disconnected from the stud, byexcessive unscrewing. or while the pen is carried about, so that thebutton cannot become lost.

When the button is screwed down (Fig. 1) it will engage the face ofbarrel 1'0, and lock the stud against axial movement, so that anuntimely compression of bag 11 is Specification of Letters Patent.

prevented. hen the button is screwed up (Fig. 3) it will become spacedfrom the barrel, so that by a pressure upon the button, the stud will beprojected into the barrel to cause the desired compression of bag 11 bybar 12.

i It will be seen that by the means de scribed, the pressure bar may beeither liberated or locked, in an efficient manner and with a minimumamount of manipulation while the headed end of the stud is permanentlyinclosed within the hollow of the button, so that the stud is not liableto be broken or to tear the pocket.

In Figs. 1-1 the button is open on top and split to increase its gripupon the stud, while in Fig. 5 the button is pear-shaped and hollow toaccommodate the stud.

I claim:

1. A fountain pen provided with a barrel, an inclosed ink bag, a presserbar engaging the bag, a threaded stud projecting outwardly from the barthrough an aperture of the barrel, and. threaded button engaging thestud, said button being chambered to accommodate the stud.

2. A fountain pen provided with a barrel, an inclosed ink bag, a presserbar engaging the bag, a threaded stud projecting outwardly from the barthrough an aperture of the barrel, a head on said stud, a button havinga tapped lower section engaging the stud and a chamber that projectsover and 1 permanently receives the head.
